Dear Leif!
Linrad continues its great evolution and I have tried to keep the 50
MHz community up-to-date
with the latest developments as I think that it is extremely usable
in that part of the spectrum.
Linrad's documentation is exemplary to other projects, but
since development is so fast, the
contents of the documents sometimes bypass the original chapter
titles. Please check below
whether any adaptation of chapter "headers" is needed (to keep the
"googling" public on track).
Maybe I interpreted some remarks too freely, or is the networking
planned for the Win-version?
Wherever you go in the Caribbean, maybe you can bring some of the
"most wanted" on the air
on 50 MHz or other bands, and at the same time put Linrad to a
tropical real world test!!
In any case I wish you a great trip and good relaxing! 73, "Zaba"

From UKSMG Announcements (January 2007):
LINRAD: like in human life names and titles may be misleading...
Though SM5BSZ's page title
reads "DSP radio for LINUX on Intel platforms", the wlr2-22 version
works these days perfectly
well with Windows (and with AMD's CPU's too, to put it
overclearly...) --- The networking feature
was gone for a while (with the transition from 1-xx single-treaded to
2-xx multi-threaded), but is
now back in the lir2-xx linux branch and will be added to future
wlr2-xx --- 73, "Zaba" OH1ZAA/2 ---

The latest Linrad 2.22 with network properties is available at the
end of the page through this link:
http://www.sm5bsz.com/linuxdsp/linroot.htm (Network not yet
implemented in the Windows-version)....
I2PHD's Winrad 1.23 (Windows only) comes through
http://weaksignals.com/ ---- On the Web you can
find several descriptions of Linrad or Winrad implementations with an
input bandwidth of 15 kHz or less,
though prefiltering weakens performance ... remember that the
man-made noise cancelling works best
with 48 kHz or wider input bandwidth. Cheap direct-conversion
I/Q-circuits work amazingly well ----
Happy New Year to you all! ---- 73, "Zaba" OH1ZAA/OHoMZA ----

OK. I can reproduce it now:-)
I always have a second file name on the line to have separate
parameters for each recording. This will be an easy fix -
but since I leave in less than 24 hours I can not fix it
immediately....

You must use the same settings for the soundcard.
Same number of channels, same sampling speed and
mode (I/Q or real-valued data) Compare the par_userint
files to see what differs between your two installations.
